DETROIT — Union workers at Ford Motor overcame early opposition to a new four-year contract with the company and overwhelmingly approved the deal in voting that lasted two weeks.

More than 26,000 workers, or 63 percent of those who cast ballots, voted in favor of the pact, while almost 15,000, or 37 percent, opposed it, the UAW said in a statement this morning.

The vote means that new contracts have been approved at Ford and General Motors, with Chrysler workers just starting to vote on their deal. At all three companies, the union agreed to profit-sharing and signing bonuses instead of annual pay raises, a novel concept that helps the companies control their costs yet rewards workers.

As part of the deal at Ford, the company promised $4.8 billion in new investments in its U.S. plants and 5,750 new jobs.

Most workers won’t get annual raises under the contract, but they will get profit-sharing checks, inflation adjustment payments and other bonuses worth at least $16,700 through 2015.
